DESCRIPTION
The AIC1953 is a dual output linear regulator
in a SOP-8 package. It is optimized for low
ESR ceramic capacitors operation and up to
600mA continuous current on each output.
The AIC1953 offers high precision output
voltage of 2%. At 600mA load current, a
470mV dropout is performed when output
voltage is equal to 3.3V. The quality of low
quiescent current and low dropout voltage
makes this device ideal for battery power
applications. The high ripple rejection and low
noise of the AIC1953 provide enhanced
performances for critical applications such as
cellular phones, and PDAs.
The AIC1953 includes current limit and thermal
shutdown protection. Each of the output is
controlled independently.
